Abstract

To fully understand the potential shortcomings of SARS-CoV-2 vaccination, it is necessary to delineate the properties of the antibodies elicited, during immunization, and also infection. Through investigation of the SARS-CoV-2 spike-reactive B cell repertoire, authors identify following infection, a subset of B cells enriched and almost exclusively target a non-neutralizing S2 epitope present in aberrant forms.
